SAM, the semi-automated mason, built by Construction Robotics:

Reminds me of the story of John Henry
A proper, memorable name for my structure hasn't been adopted yet, so...
The midwest facility of Marv's Garage Mahal was built in 1894. The walls are 12+" thick, 16' high; 100' long x 65' wide, and 3' above grade. The courses are interlaced about every 5th row, composing obviously an immense number of bricks. But not as many involved across the street. 6 stories and 600,000 square feet.
I think often about how much labor and planning went into construction of these buildings. While the video has SAM using a different variety of brick [and I'm guessing concrete masonry units could be done the same way] the work rate is rather phenomenal. No trowels, hods, mason's folding rule, hand level, loading brick carts, wow!
All the tenders might do beside feed machine is strike and brush joints.
I wonder also at cost differential, between hand laying and point machine laid is less expensive per square.
That's GARAJ Mahal and inside it sits Cecil, my mill drill, so-named because, naturally, Cecil B DeMill(e).Quote:

No profiles, stringlines, mud boards, etc and certainly "NO PIGS". NO ONE wants one of those in a structure: only recourse is demolish.
When I had a bad debt, in the early 70's, I worked a second job at nights; commercial cleaning & at weekends I was "brickies labourer". The "in" bricks were wire cut very silicone ones that ripped leather gloves like is hard to comprehend. My cut hands could hardly hold a pen or industral floor cleaner but I managed & paid my bills. I was not to realise then, that that lesson would pay me back much later. In late 80's I was building a house (17000 bricks without the future garage) and a boom in housing saw no tradies available. I finally sourced a tradie & I laboured for him and got the job done. I ended saving a lot of time & rent being able to get involved.

That's a fine idea. Not hard to replicate or use. A DIY'er can see, only the adjustments for thickness/ width of mortar bed [and volume of box] as minor issues. The demonstration lacks how they get a wet edge and finish joints; sufficient mortar is a requirement.

Masonry joints deteriorate, especially those which retain a moisture deposit. It's obvious how it occurs in raked or struck, despite tool provides smooth mortar. Flush joints are quick, but remaining surface is porous.
Would enjoy cinderblock fence after connecting single apartment with building. Gauge Hall, as it may become known, will deserve a secure perimeter. Delivering mortar as the GIF shows gets project [linear 250' 76m] back in DIY realm.
mortar looks a little too sloppy (weaker) & what about Perps? Hard to imagine that just how the "box" slides so easily. don't think they will ever really replace an experienced "brickey"! That idea is similar or based upon the kerb making machines so will have its merits in some situations.
side track.
Funny, the Thai bricks I saw were the size of an icecream-I sent a pic back to one of my brickie mates when travelling there. He was amazed at the small size & questioned the time to lay & the strength of such skinny walls. Gosh a cavity wall would be not much thicker than a mega brick single skin walls=imagine the number of cavety ties/ or rhs to support strengthen the mass.
